Flu
Shots for Travellers?
The
annual influenza “flu shot” is widely recommended for Canadians
and is covered by Manitoba Health for a variety of individuals at
high risk.
Travellers
represent a separate group of people susceptible to influenza and
should consider the flu shot for a variety of reasons.
It
is estimated that about 1% of travellers will acquire the flu while
travelling abroad. Certain situations like cruise ships and crowded
events also spread the flu quickly.
In
North America, influenza occurs largely from November to April whereas
in the Southern Hemisphere it is during our summer and their winter.
Areas located near the equator may have flu season year round.
The
flu shot of course protects us from 3 likely strains of influenza
estimated to occur in North America. This is based on analysis
of the Southern Hemisphere's most recent circulating strains. (Conversely
that is how they develop their flu strain choices based on our Northern
hemisphere flu strains). Thus the flu shot becomes available just
before the time to give it.
To
be effective flu shots should be given at least 2 weeks before travel.
Winnipegers
going to the Southern hemisphere during their winter should get
a Southern Hemisphere flu shot, which is unavailable in North America,
but would be easily available at an Australian Medical clinic when
it is both timely and appropriate to receive.
Lastly
travellers going to malarious areas may consider receiving the flu
shot to protect themselves from the flu, so they don't get flu symptoms
confused with the early symptoms of malaria or other tropical illnesses.
The
sudden occurrence of flu can make a case of malaria seem likely,
causing unnecessary tests and anxiety.
The
flu shots are available through family physicians, public health
offices and private pharmacies.
Even
if a person is not eligible under Manitoba Health guidelines they
may still purchase a shot to protect themselves while travelling
since it can prevent a significant illness during their vacation.
